From Stretcher to Dashboard: The Trauma Patient as a Data Source

Consider what happens in the first forty minutes of a major trauma case. A patient is extracted from a vehicle. Vital signs are taken at the scene, then again in the ambulance. A paramedic calls ahead. The patient arrives. A trauma team assembles, reads a paper handover form, and begins its own assessment from scratch.

In those forty minutes, an extraordinary amount of data was generated: temperature trajectory, transfer duration, pressure distribution, oxygen saturation trends, the physiological response to every intervention. All of it observed, some recorded in fragments, almost none captured in a form that could be stored, shared, or learned from. At the hospital door, it disappears.

We generate the data that could save the next patient with every transfer we do. We are then throwing it away. That is not a data problem. It is a leadership and system design problem.

What the Research Says

The evidence on information loss in trauma handovers is consistent and damning. A landmark study of 96 handovers at a Level I trauma centre found that only 72.9% of clinical information transmitted by pre-hospital teams was received and documented by hospital staff — in the controlled setting of a direct, face-to-face handover. The losses were concentrated precisely in the data that matters most:

35.7%	of recorded pre-hospital hypotension episodes received by the hospital team
45%	of Glasgow Coma Scale scores transmitted pre-hospital documented in-hospital
26.5%	of pulse rate readings transmitted by paramedics captured in hospital records

A separate study found that relying on memory alone retains only 33% of handover information. A standardised written form raises that to 99%. The technology is not the constraint — a piece of card has already been shown to triple retention. What is missing is the system that makes data capture the path of least resistance rather than an additional burden.

The pattern:  The paramedic writing vital signs on a latex glove because the tablet is too slow is not a failure of individual professionalism. It is a failure of system design.

Why Technology Alone Won't Fix It

In Transform!, I trace the consistent pattern that emerges when organisations deploy technology without first addressing the human and organisational architecture that determines whether it can actually be used.

The UK Post Office Horizon scandal is the most painful recent example: a system deployed at scale without adequate testing against real operational conditions, whose failures were blamed on the people using it rather than the system itself.

Pre-hospital data follows the same pattern. The UK air ambulance network operates across 21 independent charities, each with its own data systems and governance structures. Several digital capture initiatives have been piloted. Some have succeeded locally. None has become the standard — not because the technology was wrong, but because shared governance, aligned incentives, and the will to standardise across independent organisations were never established first.

What the Data Could Tell Us — If We Kept It

A complete longitudinal dataset of pre-hospital trauma transfers would answer questions trauma medicine currently cannot: at what point in a temperature trajectory does coagulopathy become probable? Which pre-hospital vital sign combinations most reliably predict resuscitation requirements on arrival?

A governance framework that captured and shared that data across deployments would produce evidence of a different order entirely: not 'this device addresses a known problem' but 'this device changes specific physiological trajectories in ways that correlate with outcomes.' That is the evidence that changes procurement decisions.

Every trauma transfer is an experiment. We run thousands of them every year. We are currently discarding the results.

The tools to change this exist. The governance frameworks, data standards, and cross-organisational will to use them do not yet. That is a leadership problem — and leadership problems, unlike technical ones, can be solved in a room.
